The Commands

The summary of commands for Docker Overlay Network

• docker network create tells Docker to create a new network. You use the -d overlay flag to use the overlay driver to create an overlay network. You can also pass the -o encrypted flag to tell Docker to encrypt network traffic. However, performance may drop in the region of 10%.

• docker network ls lists all the container networks visible to a Docker host. Docker hosts running in swarm mode only see overlay networks if they run containers attached to the network. This keeps network-related management traffic to a minimum.
